                                    PART I


Item 1.  Business
- -----------------

     Products and Markets:
     -------------------- 

     The primary business of the registrant and its affiliated companies is the
manufacture and sale of products designed to protect the safety and health of
workers throughout the world.

     Principal products include respiratory protective equipment that is air-
purifying, air-supplied and self-contained in design.  The registrant also
produces instruments that monitor and analyze workplace environments and control
industrial processes. Personal protective products include head, eye and face,
body and hearing protectors.

     Many of these products are sold under the registered trademark "MSA", and
have wide application for workers in industries that include manufacturing, fire
service, power generation, telecommunications, mining, chemicals, petroleum,
construction, pulp and paper processing, transportation, government, automotive,
aerospace, asbestos abatement, and hazardous materials clean-up.

     Other products manufactured and sold, which do not fall within the category
of safety and health equipment, include boron-based and other specialty
chemicals.

     The registrant and its affiliated companies are in competition with many
large and small enterprises.  In the opinion of management, the registrant is a
leader in the manufacture of safety and health equipment.

     Orders, except under contracts with the U.S. government agencies and with
international governments, are generally filled promptly after receipt and the
production period for special items is usually less than one year.  The backlog
of orders under contracts with the U.S. government agencies and certain
international governments is summarized as follows:

December 31 ------------------------- 1996 1995 1994 ------- ------- ------- (In thousands) ------------------------- U.S. Government Agencies $14,400 $30,400 $36,200 International Governments 900 7,900 8,800
Approximately $900,000 under contracts with the U.S. government agencies and $300,000 with international governments are expected to be shipped after December 31, 1997. 3 Sales of products to U.S. government agencies continued to decrease in 1996. Incoming orders were significantly less than shipments in 1996, and significantly lower than 1995 incoming orders. Further information with respect to the registrant's products, operations in different geographic areas, equity in earnings and assets of international affiliated companies, and significant customers is reported at Note 5 of Notes to Consolidated Financial Statements contained in the registrant's Annual Report to Shareholders for the year ended December 31, 1996, incorporated herein by reference. Research: -------- The registrant and its affiliated companies engage in applied research with a view to developing new products and new applications for existing products. Most of its products are designed and manufactured to meet currently applicable performance and test standards published by groups such as ANSI (American National Standards Institute), MSHA (Mine Safety & Health Administration), NIOSH (National Institute for Occupational Safety and Health), UL (Underwriters' Laboratories), SEI (Safety Equipment Institute) and FM (Factory Mutual). The registrant also from time to time engages in research projects for others such as the Bureau of Mines and the Department of Defense or its prime contractors. Registrant-sponsored research and development costs were $19,122,000 in 1996, $20,366,000 in 1995, and $20,575,000 in 1994. In the aggregate, patents have represented an important element in building up the business of the registrant and its affiliates, but in the opinion of management no one patent or group of patents is of material significance to the business as presently conducted. General: ------- The company was founded in 1914 and is headquartered in Pittsburgh, Pennsylvania. As of December 31, 1996, the registrant and its affiliated companies had approximately 4,200 employees, of which 1,900 were employed by international affiliates. None of the U.S. employees are subject to the provisions of a collective bargaining agreement. In the United States and in those countries in which the registrant has affiliates, its products are sold by its own salespersons, independent distributors and/or manufacturers' representatives. In international countries where the registrant has no affiliate, products are sold primarily through independent distributors located in those countries. 4 The registrant is cognizant of environmental responsibilities and has taken affirmative action regarding this responsibility. There are no current or expected legal proceedings or expenditures with respect to environmental matters which would materially affect the operations of the registrant and its affiliates. Generally speaking, the operations of the registrant and its affiliates are such that it is possible to maintain sufficient inventories of raw materials and component parts on the manufacturing premises. Equipment and machinery for processing chemicals and rubber, plastic injection molding equipment, molds, metal cutting, stamping and working equipment, assembly fixtures and similar items are regularly acquired, repaired or replaced in the ordinary course of business at prevailing market prices as necessary. In the third quarter of 1996, the company acquired Rose Manufacturing Company, a leading manufacturer in the growing fall protection portion of the safety products business, and Better Breathing, Inc., a leading innovator of disposable respiratory protection products. In 1992 the company decided to discontinue the operations of Transfer-Metallisierte Produkte GmbH (TMP), a joint venture in Germany to produce metallized paper. Operating activities ceased during 1993. During 1996 the company completed the assets valuation process and the settlement of its liabilities, the effects of which were not significant to the consolidated financial position and results of operations. Further information about the registrant's business is included in Management's Discussion and Analysis at pages 10 to 12 of the Annual Report to Shareholders, incorporated herein by reference. 5 Executive Officers: ------------------

                           ------------------------


          THIS TRUST AGREEMENT (the "Agreement") made effective as of June 1,
1996, between Mine Safety Appliances Company, a Pennsylvania corporation, and
PNC Bank, N.A., as trustee.

                             W I T N E S S E T H :
                             -------------------  

          WHEREAS, the Company (as defined below) desires to establish a trust
(the "Trust") in accordance with the laws of the Commonwealth of Pennsylvania
and for the purposes stated in this Agreement;

          WHEREAS, the Trustee (as defined below) desires to act as trustee of
the Trust, for the purposes hereinafter stated and in accordance with the terms
hereof;

          WHEREAS, the Company or its subsidiaries have previously adopted the
Plans (as defined below);

          WHEREAS, the Company desires to provide assurance of the availability
of the shares of its common stock necessary to satisfy certain of its
obligations or those of its subsidiaries under the Plans (as defined below);

          WHEREAS, the Company desires that the assets to be held in the Trust
Fund (as defined below) should be principally or exclusively securities of the
Company and, therefore, expressly waives any diversification of investments that
might otherwise be necessary, appropriate, or required pursuant to applicable
provisions of law, if any; and

          WHEREAS, PNC Bank, N.A., has been appointed as trustee and has
accepted such appointment as of the date set forth first above;

          NOW, THEREFORE, the parties hereto hereby establish the Trust and
agree that the Trust will be comprised, held and disposed of as follows:


                                  ARTICLE 1.
                                  ----------

                         Trust, Trustee and Trust Fund
                         -----------------------------

          1.1.  Trust.  This Agreement and the Trust shall be known as the Mine
                -----                                                          
Safety Appliances Company Stock Compensation Trust.  The parties intend that the
Trust will be an independent legal entity with title to and power to convey all
of its assets. The parties hereto further intend that the trust not be subject
to the Employee Retirement Income Security Act of 1974, as amended ("ERISA").
The Trust is not a part of any of the Plans (as herein defined).  The assets of
the Trust will be held, invested and disposed of by the Trustee, in accordance
with the

 
terms of the Trust.  The Company will not knowingly take any action that would
cause the assets held pursuant to the Trust to become "plan assets" within the
meaning of ERISA without so advising the Trustee.  The Trust is intended to be a
"grantor trust" within the meaning of Section 671 of the Internal Revenue Code
of 1986.

          1.2.  Trustee.  The trustee named above, and its successor or
                -------                                                
successors, is hereby designated as the trustee hereunder, to receive, hold,
invest, administer and distribute the Trust Fund in accordance with this
Agreement, the provisions of which shall govern the power, duties and
responsibilities of the Trustee.

          1.3.  Trust Fund.  The assets held at any time and from time to time
                ----------                                                    
under the Trust collectively are herein referred to as the "Trust Fund" and
shall consist of contributions received by the Trustee, proceeds of any loans,
investments and reinvestment thereof, the earnings and income thereon, less
disbursements therefrom.  Except as herein otherwise provided, title to the
assets of the Trust Fund shall at all times be vested in the Trustee and
securities that are part of the Trust Fund shall be held in such manner that the
Trustee's name and the fiduciary capacity in which the securities are held are
fully disclosed, subject to the right of the Trustee to hold title in bearer
form or in the name of a nominee, and the interests of others in the Trust Fund
shall be only the right to have such assets received, held, invested,
administered and distributed in accordance with the provisions of the Trust.

          1.4.  Trust Fund Subject to Claims.  Notwithstanding any provision of
                ----------------------------                                   
this Agreement to the contrary, the Trust Fund shall at all times remain subject
to the claims of the Company's general creditors under federal and state law.

          In addition, the Board of Directors and Chief Executive Officer of the
Company shall have the duty to inform the Trustee in writing of the Company's
Insolvency (as defined below).  If a person claiming to be a creditor of the
Company alleges in writing to the Trustee that the Company has become Insolvent,
the Trustee shall determine whether the Company is Insolvent and, pending such
determination, the Trustee shall discontinue allocations pursuant to Article 3.

          Unless the Trustee has actual knowledge of the Company's Insolvency,
or has received notice from the Company or a person claiming to be a creditor
alleging that the Company is Insolvent, the Trustee shall have no duty to
inquire whether the Company is Insolvent.  The Trustee may in all events rely on
such evidence concerning the Company's solvency as may be furnished to the
Trustee and that provides the Trustee with a reasonable basis for making a
determination concerning the Company's Insolvency.

          If at any time the Trustee has determined that the Company is
Insolvent, the Trustee shall discontinue allocations

                                     - 2 -

 
pursuant to Article 3 and shall hold the Trust Fund for the benefit of the
Company's general creditors.  Nothing in this Trust Agreement shall in any way
diminish any rights of employees as general creditors of the Company with
respect to benefits due under the Plans or otherwise.

          The Trustee shall resume allocations pursuant to Article 3 only after
the Trustee has determined that the Company is not Insolvent or is no longer
Insolvent as the case may be.

          1.5  Use of Trust.  The Trust Fund shall be used for the exclusive
               ------------                                                 
purpose of aiding the Company in delivering the benefits provided by the Plans
and defraying the expenses of the Trust in accordance with this Trust Agreement.
The Company may terminate the Trust in accordance with Section 8.2 hereof, but,
income or corpus of the Trust Fund is recoverable by the Company only as
provided in Section 2.2 and 8.2.

in cash on Company Stock held by the Trust, including Company Stock held in the
Suspense Account, shall be applied to pay interest and repay scheduled principal
due under the Loan.  In the event that dividends paid on Company Stock held in
the Trust, other than Extraordinary Dividends, exceed the amount of scheduled
principal and interest due in any Trust Year, such excess shall be used to
purchase additional shares of Company Stock and/or shall be distributed to a
broad cross-section of individuals employed by the Company, as determined in
good faith by the Committee.  Dividends which are not in cash or in Company
Stock (including Extraordinary Dividends, or portions thereof) shall be reduced
to cash by the Trustee and reinvested in Company Stock as soon as practicable.
For purposes of this Agreement, Company Stock purchased with the proceeds of an
Extraordinary Dividend, any excess dividend or with the proceeds of a non-cash
dividend shall for purposes of this Agreement (including without limitation
Section 3.1 hereof), be deemed to have been acquired with the proceeds of the
Loan.  In the Trustee's discretion, investments in Company Stock may be made

consent) purchases from the Company.

Suspense Account immediately before such payment or forgiveness, multiplied by a

                                     - 6 -

 
be agreed upon from time to time by the Company and the Trustee and to be
reimbursed for its reasonable legal, accounting and appraisal fees, out-of-
pocket expenses and other charges reasonably incurred in connection with the
administration, management, investment and distribution of the Trust Fund.  Such
compensation shall be paid, and such reimbursement shall be made out of the
Trust Fund.  The Company agrees to make sufficient contributions to the Trust to
pay such amounts owing the Trustee in addition to those contributions required
by Section 2.1 and, in the event the Company fails to make the contributions
necessary to pay amounts owing to the Trustee, the Trustee shall be entitled to
seek payment directly from the Company or the Trust Fund.

          4.2.  Withholding of Taxes.  The Trustee may withhold, require
                --------------------                                    
withholding, or otherwise satisfy its withholding obligation, on any
distribution which it is directed to make. The amount to be withheld shall be
such amount as the Company advises the Trustee it reasonably estimates to be
necessary to comply with applicable federal, state and local withholding
requirements.  Upon determination of the tax withholding liability, the Trustee
shall distribute the balance of the distribution to the appropriate Participant
and deliver to the Company the amount necessary to satisfy any withholding
obligation.  The Company will then deliver the withholding amount to the
appropriate governmental entity.  Prior to making any distribution hereunder,
the Trustee may require such indemnity, as the Trustee shall reasonably deem
necessary for its protection.

Fund exclusively in Company Stock, including any accretions thereto resulting

Loan shall be limited to cash and property contributed by the Company to the
Trust and dividends paid on Company Stock held in the Trust and shall not
include Company Stock acquired with the proceeds of Loan;

          (d) with the consent of the Committee, to settle, submit to
arbitration, compromise, contest, prosecute or abandon claims and demands in
favor of or against the Trust Fund;

          (e) to vote or to give any consent with respect to any securities,

with respect to any asset of the Trust Fund

                                     - 8 -

 
and to perform any and all other acts that in its judgment are necessary or
appropriate for the proper administration of the Trust Fund, even though such
powers, rights and acts are not specifically enumerated in this Agreement;

          (g) to employ such accountants, actuaries, investment bankers,
appraisers, other advisors and agents as may be reasonably necessary in

          (h) to cause any asset of the Trust Fund to be issued, held or
registered in the Trustee's name or in the name of its nominee, or in such form
that title will pass by delivery, provided that the records of the Trustee shall
indicate the true ownership of such asset;

          (i) to utilize another entity as custodian to hold, but not invest or
otherwise manage or control, some or all of the assets of the Trust Fund; and

          (j) to consult with legal counsel (who may also be counsel for the

Notwithstanding the foregoing, neither the Trust nor the Trustee shall have any
power to, and shall not, engage in any trade or business.

          5.4.  Voting and Tendering of Company Stock.
                -------------------------------------- 

          (a) Voting of Company Stock.  The Trustee shall follow the directions
              -----------------------                                          
of each Plan Participant other than Plan Participants who are members of the
Board of Directors of the Company (such non-members being hereinafter the
"Directing Plan Participants"), as to the manner in which shares of Company
Stock held by the Trust are to be voted on each matter brought before an annual
or special stockholders' meeting of the Company or the manner in which any
consent is to be executed, in each case as provided below.  Before each such
meeting of stockholders, the Trustee shall cause to be furnished to each
Directing Plan Participant, a copy of the proxy solicitation material received
by the Trustee, together with a form requesting confidential instructions as to
how to vote the shares of Company Stock held by the Trustee.  Upon timely
receipt of directions from the Directing Plan Participants, the Trustee shall on
each such

                                     - 9 -

 
matter vote the number of shares (including fractional shares) of Company Stock
held by the Trust as follows:

          The Company Stock shall be voted by the Trustee as directed by the
Directing Plan Participants with each Directing Plan Participant directing a
number of shares of Company Stock (the "Participant Directed Amount") equal to
the quotient of (x) the total number of shares of Company Stock held by the
Trust and (y) the number of Directing Plan Participants on the relevant date.
Any Shares for which the Trustee does not receive a signed voting-direction
instrument shall be voted for, against or to abstain in the same proportions as
those shares of Company Stock for which the Trustee did receive instructions.

          Similar provisions shall apply in the case of any action by
shareholder consent without a meeting.

          (b) Tender or Exchange of Company Stock.  The Trustee shall use its
              -----------------------------------                            
best efforts timely to distribute or cause to be distributed to each Plan
Participant any written materials distributed to stockholders of the Company
generally in connection with any tender offer or exchange offer, together with a
form requesting confidential instructions as to whether or not to tender or
exchange shares of Company Stock held in the Trust. Upon timely receipt of
instructions from a Directing Plan Participant, the Trustee shall tender such
Directing Participant's Participant Directed Amount if such Directing Plan
Participant has directed the Trustee to tender.  The Company will cooperate in
registering the Company Stock held by the Trust which is the subject of a tender
or exchange offer.  The Company shall be responsible for all expenses incurred
in connection with the registration of such Company Stock.

          (c) The Company shall maintain appropriate procedures to ensure that
all instructions by Directing Plan Participants in the Plans are collected,
tabulated, and transmitted to the Trustee without being divulged or released to
any person affiliated with the Company or its affiliates.  All actions taken by
Directing Plan Participants shall be held confidential by the Trustee and shall
not be divulged or released to any person, other than (i) agents of the Trustee
who are not affiliated with the Company or its affiliates or (ii) by virtue of
the execution by the Trustee of any proxy, consent or letter of transmittal for
the shares of Company Stock held in the Trust.

          5.5.  Indemnification.
                --------------- 

          (a) The Company shall and hereby does indemnify and hold harmless the
Trustee from and against any claims, demands, actions, administrative or other
proceedings, causes of action, liability, loss, cost, damage or expense
(including reasonable attorneys' fees), which may be asserted against it, in any
way arising out of or incurred as a result of its action or failure to act in
connection with the establishment, operation and administration of the Trust;
provided that such indemnification

                                     - 10 -

 
shall not apply to the extent that a court of competent jurisdiction finally
determines that the Trustee has acted (i) negligently, (ii) in violation of
applicable law or its duties under this Trust or (iii) in bad faith.  The
Trustee shall be under no liability to any person for any loss of any kind which
may result (i) by reason of any action taken by the Trustee in accordance with
any direction of the Committee or any Directing Plan Participant acting pursuant
to Section 5.4 (ii) by reason of the Trustee's failure to exercise any power or
authority or to take any action hereunder because of the failure of any such
Directing Plan Participant to give directions to the Trustee, as provided for in
this Agreement, or (iii) by reason of any act or omission of any of the
Directing Plan Participants with respect to the Trustee's duties under this
Trust.  The Trustee shall be fully protected in acting upon any instrument,
certificate, or paper delivered by the Committee or any Plan Participant or
beneficiary and believed in good faith by the Trustee to be genuine and to be
signed or presented by the proper person or persons, and the Trustee shall be
under no duty to make any investigation or inquiry as to any statement contained
in any such writing, but may accept the same as conclusive evidence of the truth
and accuracy of the statements therein contained.

          (b) The Company may, but shall not be required to, maintain liability
insurance to insure its obligations hereunder. If any payments made by the
Company or the Trust pursuant to this indemnity are covered by insurance
maintained by the Company, the Company or the Trust (as applicable) shall be
subrogated to the rights of the indemnified party against the insurance company.

          (c) Without limiting the generality of the foregoing, the Company
will, at the request of the Trustee, advance to the Trustee reasonable amounts
of expenses, including reasonable attorneys' fees and expenses, which the
Trustee advises have been incurred in connection with its investigation or
defense of any claim, demand, action, cause of action, administrative or other
proceeding arising out of or in connection with the Trustee's performance of its
duties under this Agreement.

          (d)  In no event shall the Trustee be liable for consequential
damages.

          (e)  The Trustee may initiate an action in interpleader with respect
to any issue under this Agreement and the Company shall indemnify the Trustee
from and against any reasonable legal expenses incurred by the Trustee in
connection therewith.

          5.6.  General Duty to Communicate to Committee.  The Trustee shall
                ----------------------------------------                    
promptly notify the Committee of all communications with or from any government
agency or with respect to any legal proceeding with regard to the Trust and with
or from any Plan Participants concerning their entitlements under the Plans or
the Trust.

shorter period in the case of the initial fiscal year.

year, and for such shorter periods as the Committee may reasonably request,
listing all securities and other property acquired and disposed of and all
receipts, disbursements and other transactions effected by the Trust after the
date of the Trustee's last account, and further listing all cash, securities,
and other property held by the Trust, together with the fair market value
thereof, as of the end of such period. In addition to the foregoing, the report
shall contain such information regarding the Trust Fund's assets and
transactions as the Committee in its discretion may reasonably request.

          The Committee may approve of any report furnished by the Trustee
pursuant to the foregoing paragraph either by written statement of approval
furnished to the Trustee or shall be deemed to have approved any such report by
failure to file written objection to the report with the Trustee within one
hundred and eighty (180) days of the date on which the Committee received the
report.  The Committee shall not be liable to any person for the approval,
disapproval or failure to approve or object to any report rendered by the
Trustee.

the

                                     - 12 -

no such resignation shall be effective until a successor Trustee has assumed the
office of Trustee hereunder.

          7.2.  Removal of Trustee.  The Trustee or any successor thereto may be

removed by the Company by delivering to the Trustee so removed an instrument
executed by the Committee informing the Trustee of the Committee's decision.
Such removal shall take effect at the date specified in such instrument, which
shall not be less than thirty (30) days after delivery of the instrument, unless
the Trustee accepts shorter notice; provided, however, that no such removal

                --------------------------------                              
successor thereto shall resign or be removed or a vacancy in the position shall
otherwise occur, the Company shall use its best efforts to appoint a successor
Trustee as soon as practicable after receipt by the Committee of a notice
described in Section 7.1, or the delivery to the Trustee of a notice described
in Section 7.2, as the case may be, but in no event more than sixty (60) days
after receipt or delivery, as the case may be, of such notice.  A successor
Trustee's appointment shall not become effective until such successor shall

resigning or removed Trustee shall execute all instruments and do all acts
necessary to vest title in the successor Trustee.  Each successor Trustee shall

forthwith appoint a successor Trustee in accordance with Section 7.3 to carry
out the terms of the Trust.

which such sale or transfer shall be made, shall thereupon become and be the
Trustee under the Trust with the same effect as though originally so named.

          7.7.  Continuance of Trustee's Powers in Event of Termination of the

may amend the Trust at any time and from time to time in any manner which it
seems desirable, provided that no amendment shall permit the Company to receive
any distribution prohibited by the last sentence of Section 1.5 hereof and no
amendment which would adversely affect the duties of the Trustee shall be made
without the Trustee's written consent, which consent shall not be unreasonably
withheld.  Notwithstanding the foregoing, the Company shall retain the power
under all circumstances to amend the Trust to correct any errors or clarify any
ambiguities or similar issues of interpretation in this Agreement, except to the
extent any such amendment adversely affects the duties of the Trustee.

          8.2.  Termination.  Subject to the terms of this Section 8.2, the
                -----------                                                
Trust shall terminate on the earliest of the date (i) all available shares are
distributed, (ii) on which the Loan is paid in full and (iii) the 20th
anniversary of the effective date of the Trust (the "Termination Date").  The
Company may terminate the Trust at any time prior to the Termination Date.  The
Trust shall also terminate automatically upon the Company giving the Trustee
written notice of a Change of Control.  Immediately upon a termination of the
Trust, the Company shall be deemed to have forgiven all amounts then outstanding
under the Loan.  As soon as practicable after receiving notice from the Company
of a Change of Control or upon any other termination of the Trust, the Trustee
shall sell all of the Company Stock and other non-cash assets (if any) then held
in the Trust Fund provided, that the Trustee will not be required to sell such
Company Stock unless such sale can be completed without violating applicable
securities laws.  In the event of a Change of Control or any other termination
of the Trust, the Company will cooperate in registering the Company Stock held
by the Trust.  The Company shall be responsible for all expenses

                                     - 14 -

 
incurred in connection with the registration of such Company Stock.  The
proceeds of such sale shall first be returned to the Company up to an amount
equal to the principal amount, plus any accrued interest, of the Loan that was
forgiven upon such termination.  Any funds remaining in the Trust after such
payment to the Company (the "Excess Funds") shall be used to fund (1) the
existing obligations of the Company under (i) the Plans and, then, (ii) all
broad-based employee benefit plans maintained by the Company, and (2) the
anticipated future obligations of the Company to the pre Change-of-Control
employee population under one or more broad based employee plans, and, (3) if
any Excess Funds remain, such amount shall be paid directly to the active
participants in the Company's 401(k) defined contribution plan in proportion to
each participant's base pay.  Any determination as to which plans are entitled
to funding pursuant to this paragraph or the extent of any obligation to such
plan shall be made by the Committee.

of the Trust shall be evidenced by an instrument in writing signed by an
authorized officer of the Company, certifying that said amendment or termination
has been authorized and directed by the Company or the Board of Directors, as
applicable, and, in the case of any amendment, shall be consented to by

Management's Discussion and Analysis

Sales and Earnings

Sales were $500,985,000 in 1996, a 3% increase over the prior year's
$487,668,000. Sales in 1995 were 6% higher than sales in 1994 of $459,607,000.
Net income increased 22% in 1996 to $23,061,000 from $18,912,000 in 1995, which
was 23% higher than 1994's income of $15,329,000. Earnings per share of common
stock was $4.74 in 1996, $3.32 in 1995, and $2.58 in 1994. Earnings per share
have benefitted from share repurchases that have reduced average shares
outstanding 14% in 1996 and 4% in 1995.

The 1996 sales increase occurred primarily in U.S. commercial markets, while
sales to U.S. government agencies once again decreased significantly.
International sales improved only slightly, principally in Europe. As in 1995,
commercial sales in the U.S. continue to be adversely affected by the impasse on
issuance of new Superfund and government site cleanup contracts. The 1995 sales
increase occurred primarily in the international markets, particularly in
Europe. Overall, 1995 sales by U.S. operations were about the same as 1994, with
increases in domestic commercial sales being offset by lower sales to the U.S.
government.

U.S. commercial sales increased almost 6% in 1996, as compared to increases of
4% in 1995 and 9% in 1994. Sales of instruments and specialty chemicals
sustained in 1996 the growth patterns shown in 1995 and 1994. Conversely, lower
government funding and changing customer preferences continue to reduce sales of
respiratory protection equipment. A large part of the comparative sales increase
in 1994 resulted from the acquisition of Hazco Services, Inc. in the last half
of 1993.

Sales by international operations, stated in U.S. dollars, increased 1-1/2% in
1996, 16-1/2% in 1995, and 4-1/2% in 1994. The European economic environment was
stagnant in 1996 after notable market growth occurred in Europe in 1995
following stabilization of economic conditions in 1994. Other international
markets were about the same in 1996 after significant market growth in 1995 and
1994 occurred in Australia, Brazil and Chile.

Shipments of products to U.S. government agencies in 1996 were $30,893,000, an
11% decrease from 1995 sales of $34,815,000, which were 25% lower than 1994
shipments of $46,478,000. These sales represent 6% of consolidated sales in 1996
as compared to 7% in 1995 and 10% in 1994. New contracts received in 1996 were
$14,834,000 as compared to $29,002,000 in 1995 and $27,832,000 in 1994. The 1996
year-end backlog was $14,371,000, a 53% decrease from the 1995 year-end backlog
of $30,430,000.

The 1996 gross profit rate was 38.7%, as compared to 39.1% in 1995 and 37.6% in
1994. The profitability of operations reflects cost reductions from improved
manufacturing and distribution processes, along with careful expense management.
Additionally, commercial sales carry greater margins than military sales; thus
the change of sales mix has also contributed to higher profit margins. The 1996
and 1995 gross profit have also been favorably affected by LIFO credits of
$10,361,000 and $5,455,000, respectively, arising from liquidations of LIFO
inventory values calculated at lower costs incurred in prior years, and
adversely affected by charges of $5,200,000 and $2,140,000, respectively,
arising from inventory valuation adjustments. The completion and partial
termination of some government contracts and ongoing process reengineering has
resulted in significant reductions in U.S. manufacturing inventories.

Depreciation, selling and administrative expenses were 31% of sales in 1996, 32%
in 1995, and 31% in 1994. The after-tax effects of foreign currency exchange
losses charged to income in 1996 reduced net income $667,000 or $.14 per share,
as compared to $1,279,000 or $.23 per share in 1995, and $3,840,000 or $.65 per
share in 1994. The more significant losses resulted from the currency valuation
changes that occurred in Brazil and Mexico in each of the three years. The
effective income tax rates were 37.1% in 1996, 42.9% in 1995, and 40.6% in 1994.

Restructuring

During 1996 the company initiated restructuring efforts to reduce its cost
structure and improve its competitive position. These actions included employee
reductions, writedowns for impaired assets, and facilities consolidation, the
most significant of which is the planned closing of the Esmond, Rhode Island
plant primarily because of the low level of personal protective equipment
business with the U.S. government. Commercial product activities currently
performed at Esmond will be relocated to other safety product manufacturing
facilities.

The more significant costs included in the $7,786,000 charge to 1996 operations
are:

(1) separation pay of $4,581,000, of which $1,303,000 was paid in 1996. The
number of employees affected is approximately 270, of which about 110 had
terminated as of December 31, 1996. These terminations were primarily in
manufacturing operations and administration.

(2) building, machinery and tooling writedowns, the primary non-cash provisions,
of $2,961,000.

     

                                      10



The accrued termination benefits will be paid during 1997. Other significant
cash outlays over the next one to two years will be incurred for relocation of
people and equipment, site preparation, start-up costs, and new equipment, and
will be charged to income primarily when incurred. The major portion of these
costs are expected to occur in 1997. Anticipated future benefits will result
from the reduced costs associated with a downsized production capacity better
aligned with product demands.

Restructuring charges of $730,000 in 1995 related primarily to workforce
reductions at international locations, whereas charges of $3,086,000 in 1994
were primarily applicable to completing the disposition of assets of the former
Catalyst Research Division, which was closed in 1992.


Financial Condition and Funds Flow

Cash and cash equivalents decreased $6,854,000 during 1996. Accounts receivable
increased $10,785,000 to $101,740,000 at December 31, 1996. Trade receivables
expressed in number of days sales outstanding were 71 days, as compared to 65
days in 1995. Inventories decreased $6,581,000 to $77,040,000 at December 31,
1996, resulting from completion of government contracts, improvements in
manufacturing and distribution processes, and currency exchange rate changes.
Inventory measured against sales turned 6.5 times in 1996 and 5.8 times in 1995.
The working capital ratio was 2.5 and 3.2 to 1 at years-end 1996 and 1995,
respectively.

Short-term debts of international affiliates are payable in local currencies,
which is in keeping with the company's policy of minimizing foreign currency
exposures by offsetting foreign currency assets with foreign currency debt. The
average interest rate on these loans, which include the effects of borrowing in
certain countries where local inflation has resulted in high interest rates, was
approximately 13%.

Long-term debt and the current portion thereof decreased $1,458,000 to
$15,871,000, a conservative 6% of total capital. Total capital is defined as
long-term debt plus current portion of long-term debt and shareholders' equity.

Capital expenditures were $21,583,000 in 1996, as compared to $19,136,000 in
1995. The company has continued its program of plant and equipment modernization
to increase efficiency of existing manufacturing and distribution facilities.
For the most part, capital expenditures were financed internally through
retained earnings. In the past five years, approximately $107 million has been
spent on new plants, equipment and distribution facilities.

Dividends paid on the common stock during 1996 (the 79th consecutive year of a
dividend payment) were $1.10 per share, up from the $1.06 per share paid during
1995 and $.94 per share paid
   

                                      11



    
in 1994. Cash dividends have been paid at a conservative percentage of income,
which has permitted the company to finance its growth almost exclusively through
retained earnings. During 1996, the company repurchased 601,962 common shares
for $28,853,000. As of December 31, 1996, an additional 500,000 shares may be
repurchased under current authorizations.

Credit available at year-end with banks was the U.S. dollar equivalent of
$17,157,000. The company's financial position remains strong and should provide
adequate capital resources for growth.

Cumulative Currency Translation Adjustment

The year-end position of the U.S. dollar relative to foreign currencies resulted
in translation losses of $747,000 being charged to the cumulative translation
adjustments shareholders equity account in 1996, as compared to gains of
$2,876,000 in 1995 and $5,050,000 in 1994. Significant losses occurred in
Germany and Japan, offset to some degree by gains in Australia and Britain, in
1996, while significant gains occurred in Germany in 1995 and in Australia,
Britain, and Germany in 1994.

The company's stock transfer agent is Norwest Bank Minnesota, N.A., 161 North
Concord Exchange, P. O. Box 738, South St. Paul, MN 55075-0738.

Common Stock

See notes to consolidated financial statements. 16 Notes to Consolidated Financial Statements Note 1--Basis of Presentation Significant accounting policies are stated in italics at the applicable notes to consolidated financial statements. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. All significant majority-owned companies are included in the consolidated financial statements. Investments in which the company has an equity interest of 20% to 50% are carried at equity in net assets. Intercompany transactions are eliminated in consolidation. Sales under contracts are recorded at fixed or estimated contract sales prices as deliveries are made. Contracts requiring performance over several periods are accounted for by the percentage-of-completion method of accounting. Profits expected to be realized are based on estimates of total sales and costs at completion. These estimates are periodically reviewed and revised during the contract performance period. Adjustments to profits are recorded in the period in which estimates are revised; losses are recognized in full as they are identified. Property is stated at cost. Depreciation is based on estimated useful lives using accelerated and straight-line methods. Maintenance and repairs are charged to expense. Renewals and betterments which substantially extend the useful life of property are capitalized. Profits or losses resulting from dispositions are included in income. The financial statements of companies for which the United States dollar is determined to be the functional currency are translated using current and historic exchange rates; adjustments related thereto are included in income for the current period. The financial statements of all other companies are translated from their functional currency into United States dollars using current exchange rates; the resultant translation adjustments are not included in income but are accumulated in a separate equity account. Transaction gains and losses are recognized in income for the current period. Cash and cash equivalents in the Consolidated Statement of Cash Flows includes temporary investments that are readily marketable and have minimal risk as to change in value. Certain securities have maturities in excess of ninety days; but, as part of the company's cash management program, maturities are scheduled based on expected cash needs for the ensuing twelve months. Earnings per share is computed based upon the weighted average number of common shares outstanding during each year. Shares held by the stock compensation trust that have not been committed to be released are not considered as outstanding shares. The computation recognizes dividends paid on preferred stock but does not include a negligible dilutive effect of stock options. Note 2--Other Income
Other income is summarized as follows: (In thousands) ------------------------- 1996 1995 1994 ------------------------- Interest $ 2,628 $3,585 $3,043 Commissions, royalties and product services 1,944 1,959 1,940 Dispositions of assets 1,725 (320) 103 Equity in earnings of affiliates 656 (451) 212 Other (1,083) (582) 165 ------------------------- Total 5,870 4,191 5,463 -------------------------
Note 3--Inventories The U.S. inventories are valued on the last-in, first-out (LIFO) cost method. Other inventories are valued at the lower of cost, using average or current standard costs which approximate actual costs on a first-in, first-out (FIFO) basis, or market, determined by replacement cost or net realizable value. Significant reductions of domestic inventories during 1996, 1995 and 1994 caused liquidations of LIFO inventory values calculated at lower costs incurred in prior years. The effect of these liquidations has been to reduce cost of sales by $10,361,000 in 1996, $5,455,000 in 1995 and $6,923,000 in 1994, and to increase net income by $6,217,000 ($1.28 per share), $3,200,000 ($.56 per share) and $4,189,000 ($.71 per share), respectively. Inventories are summarized as follows:
(In thousands) ------------------------- 1996 1995 1994 ------------------------- Finished products $32,042 $34,970 $33,576 Work in process 15,311 16,135 14,013 Raw materials and supplies 29,687 32,516 29,377 ------------------------- Total inventories 77,040 83,621 76,966 ------------------------- Excess of FIFO costs over LIFO costs 45,740 55,185 59,178 -------------------------
Inventories stated on the LIFO basis represent 39%, 39%, and 43% of the total inventories at December 31, 1996, 1995, and 1994, respectively. Note 4--Long-Term Debt

Approximate maturities of these obligations over the next five years are $2,593,000 in 1997, $1,142,000 in 1998, $404,000 in 1999, $330,000 in 2000, and $326,000 in 2001. Some U.S. loan agreements contain covenants to maintain specified levels of shareholders' equity. 17 Note 5--Business Segments and International Operations The company is primarily engaged in the manufacture and sale of safety and health equipment. Principal products include respiratory protective equipment, head protection, eye and face protection, hearing protectors, safety clothing, industrial emergency care products, mining safety equipment and monitoring instruments. These safety and health products account for more than 90% of revenues, operating profits and assets. Other products which do not fall within the safety and health equipment segment of the company's business include boron- based and other specialty chemicals. Information about the company's operations in different geographic areas is summarized as follows:

Transfers between geographic areas are stated at established intercompany selling prices. Operating profit is total revenues less operating expenses. Interest income and expense, equity in unconsolidated affiliates, facilities consolidation and restructuring charges, contract costs recovery, and income taxes have not been included in computing operating profit. Corporate assets not included in identifiable assets are principally cash and investments. Sales by U.S. operations to U.S. government agencies were $30,893,000 in 1996, $34,815,000 in 1995, and $46,478,000 in 1994. Note 6--Restructuring Restructuring charges of $7,786,000 in 1996, most of which relate to the planned closing of the company's Esmond, Rhode Island safety products manufacturing facility, include $4,581,000 for separation pay to approximately 270 employees and $2,961,000 for impaired assets. Charges of $730,000 in 1995 related primarily to workforce reductions at international locations, and 1994 charges of $3,086,000 applied primarily to disposition of assets of the Catalyst Research Division, which was closed in 1992. Note 7--Research and Development Expense Research and development costs, charged against income as incurred, were $19,122,000 in 1996, $20,366,000 in 1995, and $20,575,000 in 1994. 18 Note 8--Income Taxes Income taxes are accounted for in accordance with Statement of Financial Accounting Standards No. 109. Deferred tax balances are stated at tax rates expected to be in effect when taxes are actually paid or recovered. No provision is made for undistributed earnings of international companies since little or no tax would result under applicable existing statutes or because management intends that these earnings be permanently reinvested for working capital and capital expenditure requirements. The U.S. and non-U.S. components of income before income taxes, and provisions for income taxes are summarized as follows:

Second cumulative preferred voting stock--none has been issued. As to the 4-1/2% cumulative preferred stock, 71,373 shares have been issued (none during the three years ended December 31, 1996), while the amounts held in treasury at each year end are 1996 - 49,313 shares, $1,595; 1995 - 47,935 shares, $1,553; and 1994 - 47,775 shares, $1,548. The company has established the Mine Safety Appliances Company Stock Compensation Trust, the purpose of which is to fund certain benefit plans, including employee stock options and awards. In June 1996, the company sold 600,000 treasury shares, at market value, to the Trust, in exchange for a $28,200,000 promissory note, 8% interest, payable to the company. On February 10, 1997, the company adopted a Shareholder Rights Plan which includes distribution of rights as a dividend at the rate of one right for each share of the company's common stock owned on February 21, 1997. Each right will entitle the holder to buy a fraction of a share of a participating preferred stock for $225 in the event certain persons or groups acquire 15% or more of the company's outstanding common stock. Each right will entitle its holder to purchase common stock having a value twice the exercise price. These rights will expire on February 21, 2007. Note 10--Leases The company leases warehouses, sales offices, manufacturing facilities and equipment under agreements expiring at various dates through 2001, with renewal options existing for varying periods. Rental expense for these leases charged to income was $6,956,000 in 1996, $6,970,000 in 1995, and $6,452,000 in 1994. Future minimum rental commitments under noncancelable leases are not significant.

20 Note 12--Short-Term Debt Short-term bank lines of credit amounted to $19,131,000 of which $17,157,000 was unused at December 31, 1996. Generally, these short-term lines of credit are renewable annually and there are no significant commitment fees or compensating balance requirements. Short-term borrowings with banks, which exclude the current portion of long-term debt, were $5,491,000 and $3,362,000 at December 31, 1996 and 1995, respectively. The average month-end balance of total short- term borrowings during 1996 was $2,912,000 while the maximum month-end balance of $5,491,000 occurred at December 31, 1996. The average interest rate during 1996 was approximately 13% based upon total short-term interest expense divided by the average month-end balance outstanding, and 18% at year-end. This average interest rate is affected by borrowings in certain countries where local inflation has resulted in relatively high interest rates. Note 13--Retirement Plans Substantially all employees are covered by non-contributory pension plans. Various U.S. employees also participate in a contributory retirement savings plan wherein employees may contribute from 1% to 10% of their compensation to a trust fund, to which the company contributes an amount equal to 50% of the employees' contributions not in excess of 8%. The company's expense for these plans was $2,798,000 in 1996, $3,069,000 in 1995, and $4,647,000 in 1994. The non-contributory pension plans are accounted for in accordance with Statement of Financial Accounting Standards No. 87 which requires use of the projected unit credit cost method to determine the projected benefit obligation and plan cost. The principal U.S. plan is funded in compliance with the Employee Retirement Income Security Act (ERISA). It is the general policy to fund current costs for the international plans except in Germany, where it is common practice and permissible under tax laws to accrue book reserves. Non-contributory plan benefits are generally based on years of service and employees' compensation during the last years of employment.

21 Note 14--Postretirement Benefits The company provides certain health care benefits and limited life insurance for retired employees and their eligible dependents, the costs for which are accounted for in accordance with Statement of Financial Accounting Standards (SFAS) No. 106. SFAS No. 106 requires recognition of retiree health and life insurance benefits during the employees' service with the company. Further information about these benefits is provided in the following tables.
Cost for Benefits (In thousands) 1996 1995 1994 - -------------- --------------------------- Service cost--benefits earned during the period $ 408 $ 349 $ 471 Interest cost on projected benefit obligation 1,152 1,168 1,198 Amortization of (gain)/loss 40 Special benefit adjustments associated with early retirement and restructuring 36 (247) --------------------------- Retirement benefits expense 1,596 1,270 1,709 --------------------------- Funded Status and Accumulated Postretirement Benefit Obligation Reconciliation December 31 (In thousands) - -------------------------- Accumulated postretirement benefit obligation Active employees 3,214 3,352 3,188 Other active participants 6,955 7,224 6,098 --------------------------- 10,169 10,576 9,286 Retirees 6,268 6,031 5,389 --------------------------- Total 16,437 16,607 14,675 Unamortized (loss) (1,431) (2,241) (222) --------------------------- Accrued postretirement benefit cost included in consolidated balance sheet 15,006 14,366 14,453 --------------------------- Assumed discount rates for future benefits 7-1/2% 7-1/4% 8-1/4% ---------------------------
Annual rates of increase in the costs of covered health care benefits assumed for 1996 were 7%, decreasing gradually to 4% for the year 1999 and thereafter. The health care cost trend rate assumption has a significant effect on the amounts reported; a one-percentage-point increase in each year would increase the accumulated postretirement benefit obligation by $1,157,000 and increase the current service and interest costs for the year by $147,000. Note 15--Stock Plans The company's Management Share Incentive Plan permits the granting of restricted stock awards and stock options to eligible key employees through December 1997. The 1990 Non-Employee Directors' Stock Option Plan provides for annual grants of stock options to eligible directors. As of December 31, 1996, there were 257,090 shares and 37,800 shares, respectively, reserved for future grants pursuant to these Plans. Stock options are generally granted at market value option prices and expire after ten years (limited instances of option prices in excess of market value and expiration after five years). Restricted stock awards are granted (17,050 shares in 1996) to employees without payment to the company in consideration of services to be performed in ensuing five-year periods. The company applies Accounting Principles Board Opinion No. 25 and related Interpretations in accounting for the Plans. Accordingly, no compensation cost has been recognized for the stock option grants. Compensation cost for the restricted stock awards is measured by the market value of the shares when awarded and is amortized by charges to operations over the period that the employee provides the service. The expense charged to operations was $350,000 in 1996, $238,000 in 1995, and $413,000 in 1994. The company's net income and earnings per share would not be significantly affected if compensation cost for these Plans was determined based on fair value at grant dates consistent with the method provided in Statement of Financial Accounting Standards No. 123. A summary of the two stock option plans follows:
1996 1995 1994 ------------------------------------------------------------------------------------ Weighted-Average Weighted-Average Weighted-Average Shares Exercise Price Shares Exercise Price Shares Exercise Price ------------------------------------------------------------------------------------ Outstanding at beginning of year 46,360 $46.18 49,260 $45.89 32,520 $48.31 Granted 31,455 46.37 3,000 44.00 20,140 44.59 Exercised (13,840) 43.49 (5,900) 42.62 Forfeited (5,610) 47.50 (3,400) 61.33 ------------------------------------------------------------------------------------ Outstanding at end of year 58,365 46.77 46,360 46.18 49,260 45.89 ------------------------------------------------------------------------------------ Options exercisable at year-end 58,365 44,473 45,101 ------------------------------------------------------------------------------------
The options outstanding at December 31, 1996 have a weighted-average remaining contractual life of approximately 7.3 years and an exercise price range of $40.43 to $55.75. 22 FIVE-YEAR SUMMARY OF SELECTED FINANCIAL DATA
